No, this is used to create an Arrow schema from `StructType` in `ArrowUtils 
.toArrowSchema()`, too.

I agree that it'd be better to refactor `ColumnVector`, but I think 
`ColumnVector` is related to `ColumnarBatch` or other classes, so we should do 
it, and also refactor `ColumnarBatch` at the same time, in the future PRs.

[GitHub] spark issue #18652: [WIP] Pull non-deterministic joining keys from Join oper...

2017-07-19 Thread viirya
Github user viirya commented on the issue:

https://github.com/apache/spark/pull/18652
  
I just checked with Hive's behavior (2.1.0). I tried a query like `select * 
from l left outer join r on rand(l.a) > 0.1 and rand(cast(l.b as int)) > 0.2 
and rand(r.c) > 0.2 and rand(cast(r.d as int)) > 0.5;`.

The conditions `rand(r.c) > 0.2 and rand(cast(r.d as int)) > 0.5` are 
pushed down to Filter operator.

  TableScan
alias: r
Statistics: Num rows: 2 Data size: 10 Basic stats: COMPLETE 
Column stats: NONE
Select Operator
  expressions: c (type: int), d (type: double)
  outputColumnNames: _col0, _col1
  Statistics: Num rows: 2 Data size: 10 Basic stats: COMPLETE 
Column stats: NONE
  Filter Operator
predicate: ((rand(UDFToInteger(_col1)) > 0.5) and 
(rand(_col0) > 0.2)) (type: boolean)
Statistics: Num rows: 1 Data size: 5 Basic stats: COMPLETE 
Column stats: NONE
HashTable Sink Operator
  filter predicates:
0 {(rand(_col0) > 0.1)} {(rand(UDFToInteger(_col1)) > 
0.2)}
1 
  keys:
0 

The other conditions `rand(l.a) > 0.1 and rand(cast(l.b as int)) > 0.2` are 
filter predicates with the Join operator.

  Map Join Operator
condition map:
 Left Outer Join0 to 1
filter predicates:
  0 {(rand(_col0) > 0.1)} {(rand(UDFToInteger(_col1)) > 
0.2)}
  1 
keys:
  0 
  1 

A query `select * from l left outer join r on rand(l.a) = rand(r.c);` with 
non-deterministic joining keys. There's no push down. Hive simply evaluates the 
joining keys.

  Map Join Operator
condition map:
 Left Outer Join0 to 1
keys:
  0 rand(_col0) (type: double)
  1 rand(_col0) (type: double)
outputColumnNames: _col0, _col1, _col2, _col3

I see, I'll modify it to accept `dataType` but I guess we shouldn't pass it 
to `ColumnVector` to avoid illegally allocating child columns.

[GitHub] spark issue #16924: [SPARK-19531] Send UPDATE_LENGTH for Spark History servi...

2017-07-19 Thread viirya
Github user viirya commented on the issue:

https://github.com/apache/spark/pull/16924
  
In `FsHistoryProvider`, since there is a check for file size, I think it is 
designed to find updated logs from running applications?


https://github.com/apache/spark/blob/e26dac5feb02033f980b1e69c9b0ff50869b6f9e/core/src/main/scala/org/apache/spark/deploy/history/FsHistoryProvider.scala#L331

Btw, in `EventLoggingListener`, if it writes to local files, seems to me 
the file length will be updated and so `FsHistoryProvider` can find the updated 
logs.

Seems this looks reasonable to make the non local fs functionally 
consistent with local fs.

It does not really check it explicitly .. does it? It tests it implicitly

[GitHub] spark issue #18664: [SPARK-21375][PYSPARK][SQL][WIP] Add Date and Timestamp ...

2017-07-19 Thread BryanCutler
Github user BryanCutler commented on the issue:

https://github.com/apache/spark/pull/18664
  
@ueshin @holdenk I think I'm seeing an issue with transferring timestamp 
data to Pandas with Arrow, so I'll try to explain.  Spark will assume the 
timestamp is in local time, so when converting to internal data, it will adjust 
with an offset to UTC from local timezone.  Currently, the internal data is 
converted to Arrow without a timezone, which Arrow takes as timezone unaware.  
When a Pandas DataFrame is created from that data, it does not adjust to local 
time, so a different timestamp is shown.  For my case below, using PST as local 
time, it will add 8 hours.

```

In [2]: dt = datetime.datetime(1970, 1, 1, 0, 0, 1)

In [5]: TimestampType().toInternal(dt)
Out[5]: 2880100

In [8]: df = spark.createDataFrame([(dt,)], 
schema=StructType([StructField("ts", TimestampType(), True)]))

In [7]: df.show()
+---+
| ts|
+---+
|1970-01-01 00:00:01|
+---+

In [9]: spark.conf.set("spark.sql.execution.arrow.enable", "true")

In [10]: df.toPandas()
Out[10]: 
   ts
0 1970-01-01 08:00:01

In [11]: spark.conf.set("spark.sql.execution.arrow.enable", "false")

In [12]: df.toPandas()
Out[12]: 
  ts
0 1970-01-01 00:00:01
```

It wasn't a problem before Arrow because the data gets converted before 
going into Pandas.  I believe there are a few different ways to handle this

1) Adjust the Spark internal data to represent local time, not UTC time, 
and create an Arrow field without specifying the timezone.

2) Give the Arrow field the timezone from `DateTimeUtils.defaultTimeZone()` 
and adjust the internal data to represent local time, not UTC time.

3) Give the Arrow field a "UTC" timezone, then no adjustments need to be 
done to the internal data but I think Pandas will still display as UTC and it 
would be up to the user to change timezone.

I'm not sure what the best solution is because there could be issues with 
them all, any thoughts?
